At physiological level, flooding modifies water relations and plants carbon fixation. Closing of stomata, with or without leaf dehydration, reduction of transpiration and inhibition of photosynthesis, are responses that can occur in hours or days, depending on the tolerance to flooding of each plant species (Bradford & Hsiao, 1982;

Nov 5, 2014 · It describes the main problems plants face with too much water like low oxygen levels. It outlines strategies plants use to tolerate flooding, including root adaptations like aerenchyma tissue to transport oxygen and shoot adaptations like elongation to grow above water.
Dec 26, 2021 · Flooding causes detrimental effects on plant metabolism, photosynthesis, and nutrient and water relations. It reduces aerobic respiration and the production of ATP in roots. Photosynthesis decreases due to stomatal closure and inhibition of photosynthetic enzymes.
Aug 24, 2018 · Flooding stress restricts gas diffusion in and out of the plant cells, and subsequently leads to oxygen deficiency inside the plants. Plants can react to flooding with two strategies. On one hand, they can avoid the occurrence of oxygen deficiency inside by anatomical and morphological adaptations.

Mar 28, 2011 · Flooding is a compound stress composed of interacting changes inside plant cells induced by the flood water surrounding the plant. The concentrations of oxygen (O 2), CO 2, reactive oxygen species (ROS) and ethylene change upon flooding and can occur in various combinations, as determined by the flooding regime.
